Voting patterns of America’s whites, from the masses to the elites — The Monkey Cage: If you define elites as high-income non-Hispanic whites, the elites vote strongly Republican. If you define elites as college-educated high-income whites, they vote moderately Republican.
There is no plausible way based on these data in which elites can be considered a Democratic voting bloc. To create a group of strongly Democratic-leaning elite whites using these graphs, you would need to consider only postgraduates (no simple college grads included, even if they have achieved social and financial success), and you have to go down to the below-$75,000 level of family income, which hardly seems like the American elites to me.
